Agent Builder

🤖 **AI Agent Builder (Sub-process #3)**

1. **Chat Trigger** – waits for a user request (e.g. in GPT-style chat).
2. **AI Agent (LangChain)** – orchestrates:
   • **OpenRouter GPT-4o** (LLM)
   • **SerpAPI** (web-search tool)
   • **Pinecone Vector Store** (RAG)
   • **Structured Output Parser** to guarantee valid JSON.
3. **OpenAI (validator)** – double-checks the JSON and pretty-prints errors.
4. **Code → Convert to File** – extracts the final template and returns it as a downloadable file.

Result: a fully wired n8n workflow template matching the user’s prompt.
